Hi, I'm a little confused by the sub-shells that electrons orbit in. The first sub-shell is S(harp) and that can hold 2 electrons. The two elements that have (only) this sub-shell are: Hydrogen, Helium.
The Next is P(rinciple) and it can hold 6 electrons. The elements that have (only S and) this shell are: Lithium, Beryllium, Boron, Carbon, Oxygen, Nitrogen, Fluorine and Neon.
This shell works by filling up the S shell first, and then the P shell.
The next is D(iffuse) and that can hold 10 electrons. This is where I get confused, as before, the sub-shells only contained the elements that were in one period, but it seems to me that this can contain many more, as the sum of the 3 sub-shells is 18. Am I right to assume that the last element containing only the D sub-shell and those below it is nickel?
Can you tell me if it is, and why... because this next part confuses me too.
There are 4 sub-shells that have names; Sharp, Principle, Diffuse and Fundamental. There are a few after that without names; G, H and I. If you pack the electrons in the Fundamental sub-shell until it is completely full, then you stop the Fundamental sub-shell at Neodymium (Nd). If you then go on to continue with the other sub-shells (G, H, and I) (Assuming G has 18 electrons at max) you end the G sib-shell at Ununnilium (Uun) You then can't fill up the H sub-shell because there simply isn't enough elements one the periodic table to occupy it! If you can't fill up H, then hat's the point of making an I sub-shell?
QUESTIONS I WANT ANSWERED:
Is the last element containing sub-shell D (and below) Nickel?
Am I correct assuming that sub-shell G can hold 18 electrons at max?
Does the F sub-shell stop at Neodymium?
Is the rest of what I have said correct?
Thank you in advance!
